2022 Ultimate Shampoo Comparison – What Are The Best Shampoos For Hair Growth & Thickness?

Every year, millions of people have to deal with the chronic struggle of losing their hair and dealing with hair thinning.

And yet, few stop to consider the impact their shampoo has on the structure and density of their hair.

According to dozens of recent clinical studies, the shampoo you use can have a massive impact on the thickness and appearance of your hair — and can even help to promote hair growth, especially when combined with synergistic products.

In fact, most people aren’t aware that the shampoo they use and think is good for them can actually make things worse and trigger rapid hair loss — without realising it!

In today’s guide, our editorial team has conducted a detailed analysis of over 30 different shampoos to find the 4 best ones. We then followed it up with another round of tests to rank these 4 shampoos from best to worst, so you can make an informed decision.

First, we look at several key details and facts everyone needs to know about their shampoo.

The Hidden Link Between Your Shampoo & Hair Loss

When it comes to hair loss, few people suspect that their shampoo might play a role. We all think about genetics and perhaps our diet and lifestyle contributing to hair loss — but the truth is, our shampoo can play a major role in triggering hair loss and hair thinning.

Here’s why — scientists now know that most shampoos contain dozens of dangerous toxins and additives. These products are used to make the shampoo easier to produce and last longer. But they’re used at the expense of the health of your hair!

Think of it this way — it’s just like using dangerous pesticides on fertile soil. In the short term, things work well — but in the long term, it damages the quality of the soil. The same phenomenon is true for shampoos and your hair. In the short term, they may feel good — but ultimately, they only damage your hair follicles.

But why exactly can your shampoo be involved in hair loss? Well, it has to do with hair follicles and their function. When toxic substances in conventional shampoos reach your scalp, they get absorbed and can damage your hair follicles — the tiny structure responsible for growing your hair.

Over time, this will lead to thinning hair and may even contribute to hair loss.

Key Things To Look For In A Quality Shampoo To Fight Hair Loss

Criteria #1 – Must contain the right blend of amino acids to stimulate keratin

Keratin is an essential building block of your hair — any lack of keratin can lead to hair falling out and problems with hair growth. This is why it’s essential to make sure your shampoo has the right blend of amino acids proven to lead to increases in keratin levels, ideally backed by clinical studies.

Criteria #2 – Must contain niacinamide

Niacinamide, also known as vitamin B3, is a powerful B vitamin that has powerful effects when applied to hair follicles and hair scalp. It’s notably also proven to increase keratin levels, and can lead to strengthened hair follicles naturally.

Criteria #3 – Must contain the right ingredients to stimulate hair regeneration

If you want your shampoo to have active, therapeutic effects – make sure it has the ingredients to do it. This is why high-quality shampoos always include ingredients that stimulate hair follicles and help regenerate your hair naturally.

Criteria #4 – Must not contain any artificial chemicals or additives

Quality shampoos must be naturally derived — which means that they don’t contain artificial substances and chemicals. This helps avoid the problem discussed earlier – namely, that chemicals can cause long-lasting damage to your hair follicles, which is directly linked to hair loss.

The 4 best hair growth products on the market today

After hours of intensive research, and considering combined ratings and online reviews from customers like you, we’ve compiled a list of the top four hair growth shampoos on the market.

1: Scandinavian Biolabs’ Hair Strength Shampoo

THE BOTTOM LINE

Scandinavian Biolabs’ Hair Strength Shampoo is made by the trusted Danish brand Scandinavian Biolabs. It was designed with science, safety and effectiveness in mind — by combining a special blend of amino acids with niacinamide to promote healthy keratin levels, one of the key things we look for in a quality hair strength shampoo.

Its main differentiation however is the fact that it contains small doses of Scandinavian Biolabs’ special ingredient Capilia Longa. Designed by a biotech lab in Spain, this special ingredient has been clinically proven to promote hair regeneration and hair strength naturally without side effects.

The entire formula of the shampoo is naturally derived, and it’s free of chemical preservatives and additives, making it a safe formula to use over the long term. This combination of strengths makes it the leading product in our rankings.

PROS

  • Powerful amino acid and niacinamide blend to promote healthy keratin levels
  • Special ingredient Capilia Longa can promote hair regeneration
  • Naturally derived, free of artificial chemicals and preservatives
  • 150-day money-back guarantee

CONS

  • Frequently runs out of stock

2: Hairburst Hair Growth Shampoo

THE BOTTOM LINE

Hairburst’s Hair Growth Shampoo contains a blend of amino acids proven to promote healthy keratin levels — one of the key things to look for in a hair strength shampoo.

It also contains Panthenol, a special ingredient that can help retain water on the hair shaft to improve the appearance and feel of the hair. Free of paraben and silicone, it’s an all-natural formula free of preservatives and additives.

The only criticism our team had of the formula is the lack of ingredients specifically made to promote hair growth. Overall, Hairburst’s product is a solid formula that will limit the damage of conventional shampoos.

PROS

  • Amino acid blend to promote healthy keratin levels
  • Panthenol can retain water on the hair shaft to improve hair texture
  • Silicone and paraben-free, all-natural formula

CONS

  • Lack of ingredients specifically for hair growth

3: ThickTails Hair Growth Shampoo

THE BOTTOM LINE

ThickTails’ Hair Growth Shampoo is a shampoo containing biotin, a key B vitamin that plays an important role in hair density and fullness — along with caffeine to promote hair vitality. It also contains saw palmetto to block DHT, a hormone often associated with hair loss.

It’s free of paraben and silicone as well as other artificial ingredients. The only regrettable fact about ThickTails’ product is that caffeine doesn’t specifically help with hair growth, and the overall formula is on the expensive side given the lack of scientific evidence for the active ingredients.

PROS

  • Biotin can help promote hair fullness
  • It May help reduce DHT levels
  • Silicone and paraben-free

CONS

  • Lack of scientific evidence for the active ingredients
  • Caffeine doesn’t provide hair growth benefits

4: Plantur 21 #longhair Caffeine Shampoo

THE BOTTOM LINE

As the last product in our ranking, Plantur 21 lags behind. As a caffeine formula containing biotin, zinc and magnesium, the product seems appealing —but unfortunately, it does not contain any ingredient proven to boost hair growth.

It remains a good formula, but will not have the same effects to fight hair loss as the other products in our rankings.

PROS

  • Silicone and paraben-free
  • Biotin can promote healthy keratin levels

CONS

  • Lack of scientifically proven hair growth ingredients
  • Overall weaker formula
